Endovascular aneurysm repair (EVAR) has become an established therapy for many patients with abdominal aortic aneurysms. This minimally invasive procedure has lower operative mortality and similar long-term survival rates compared to open surgical treatment. However, several patients are still unsuitable for EVAR because of their aneurysm neck or iliac(More)
PURPOSE No consensus exists on the optimal treatment of acute malignant right-sided colonic obstruction (RSCO). This systematic review aims to compare procedure-related mortality and morbidity rates between primary resection and stent placement as a bridge to surgery followed by elective resection for patients with acute RSCO. METHODS PubMed, Embase and(More)
OBJECTIVES Reference values of aortic deformation during the cardiac cycle can be valuable for the pre-operative planning of thoracic endovascular aortic repair (TEVAR) and for facilitating computational fluid dynamics. This study aimed to quantify normal aortic extensibility (longitudinal extension) and distensibility (radial expansion), as well as(More)
BACKGROUND Aortic stiffness is an independent predictor of cardiovascular mortality. In this study, the effect of thoracic endovascular aortic repair (TEVAR) on aortic stiffness is investigated by measuring aortic pulse wave velocity (PWV) in an ex vivo porcine model. METHODS Fifteen fresh porcine thoracic aortas were connected to a benchtop pulsatile(More)
BACKGROUND Currently, the optimal management strategy for chronic type B aortic dissections (CBAD) is unknown. Therefore, we systematically reviewed the literature to compare results of open surgical repair (OSR), standard thoracic endovascular aortic repair (TEVAR) or branched and fenestrated TEVAR (BEVAR/FEVAR) for CBAD. METHODS EMBASE and MEDLINE(More)
OBJECTIVES To quantify the impact of thoracic endovascular aortic repair (TEVAR) on radial aortic strain with the aim of elucidating stent-graft-induced stiffening and complications. METHODS Twenty fresh thoracic porcine aortas were connected to a mock circulatory loop driven by a centrifugal flow pump. A high-definition camera captured diameters at five(More)
OBJECTIVE This study assessed whether the additional use of the aortic arch classification in type I, II, and III may complement Ishimaru's aortic arch map and provide valuable information on the geometry and suitability of proximal landing zones for thoracic endovascular aortic repair. METHODS Anonymized thoracic computed tomography scans of healthy(More)
BACKGROUND To improve early diagnostic and therapeutic decision making, we designed the HEART score for chest pain patients in the emergency department (ED). HEART is an acronym of its components: History, ECG, Age, Risk factors and Troponin. Currently, many chest pain patients undergo exercise testing on the consecutive days after presentation. However, it(More)
